Solving ifort/IFX runtime issues

[fedebenelli]

When compiling with ifx and ifort there is a problem (at least on my PC, since it seems to work ok over Github CI) when tracing phase envelopes. Where the passed function foo from the pt_envelope_2ph function to the continuation function provides a wrong reference.

As it was seen on the optimization API changes, it seems that ifx does not behave well when passing a procedure that was defined inside another procedure

subroutine foo(x, y)
    call hoo(goo, x, y)
contains
    subroutine goo(x, y)
    end subroutine
end subroutine

Maybe there is some kind of relation here
